CHIMNEY CLOSURE AND VENTILATOR.

Specification of Letters Patent.

Patented Nov. 20. 1906.

Application filed June 29, 1905. Serial No. 267,620.

of this invention is to provide a class which may be quickly and conveniently secured within a chimney-flue opening of the ordinary construction and present new and improved features of convenience and reliability.

A further object of this invention is to provide a ventilating-closure for chimneyopenings and embodying a perforate diaphragm extending entlrely across the opening and arranged to prevent the passage of soot and other material.

A further object of this invention is to provide a closure for a chimneyopening mounted upon a screw extending w1th1n the opening and having a depending endless chain to rotate the closure and screw, and thereby open the closure.

With these and other objects in view the present invention consists in the combina tion and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes 1n the form, proportion, size, and minor deta ls may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawlngs, Figure 1 is a vertical sectional view of the chimney closure and ventilator forming the subjectmatter of this application. Fig. 2 is a view of the chimney closure and ventilator shown in perspective.

Like characters of reference designate corresponding parts throughout both views,

In its preferred embodlment the 1mproved chimney closure and ventilator forming the subject-matter of th1s a plication is adapted to be mounted in a c mney 1, of ordinary construction, having the usual ihimble 2, and consists of a tubular member tending transversely of the tube 3 at the inner end and also near the outer end are transverse brace-bars 5, and mounted for rotation through these bars are rods 4, with the inner ends bent laterally at 6 and the outer ends bent into handles 7. The bent ends 6 are designed to bear against the inner face of the chimney 1, when the rods are disposed in one position, by operating the handles 7, as shown in Fig. 1, to lock the tubular member 3 and its attachments in the thimble, and releasable by reversing the position of the rods, as will be obvious. The tubular member 3 extends beyond the outer face of the chimney and is provided with an outwardly-extending bead 8, which is utilized to support a collar 9 of the usual construction for bearing against the wall adjacent to the chimney-opening and provide a finish to the device. By this arrangement the collar and holding-bead coact to prevent the tubular member from being thrust too far into the chimney, and the rods 4 prevent the withdrawal of the same.

The braces 5 are provided with openings disposed centrally of the tube 3, within which is mounted a screw 10, extending axially of the tube. The inner end of the screw 10 is provided with a knob 11 or other means for preventing the complete removal of the screw from the braces, and upon the outer end of the screw is mounted a cover member 12, with the screw 10 serving as an axis, and provided with a flange 13, arranged to fit over and close the outer end of the tube 3. The screw 10 is preferably formed of two twisted wires, as shown. Upon the outer surface of the cover member 12 and concentric therewith is mounted a dished corrugated disk 14, secured in any convenient manner, as by the knob 15, and in the groove formed between the outstanding flange of the disk 14 and the cover member 12 is loosely disposed a chain 16, depending to any desired distance for convenience of manipulation. Within the tube 3 is disposed a perforate diaphragm 17, preferably composed of wire fabric and dishshaped and preventing the escape of soot, ashes, and similar matter.

From the foregoing description it will be understood that the manipulation of the chain 16 will rotate the cover 12, with the screw 10 as an axis, and that the rotation of the screw 10 will move the cover nearer to or farther from the outer end of the tube 3,

according ,to the direction in which the cover I ing-apertures and bent laterally at one end is rotated, and that when the cover is open I for bearing against the inner face of the 15 prevent the chimney and with lateral handles at the passage through the ventilator of soot or other ends operative from the outer end of other material. v l the thimble.
